There are many strategies that can be employed to multiply and divide larger numbers. Students will deepen their conceptual knowledge of multiplication and division, starting with visual models like arrays and diagrams.Then students will then move to more abstract calculation methods like partial products, the distributive property and standard algorithms.
Facilitate an exploration and comparison of multiplication strategies for your students to see the variety of ways to solve the same problem. Use this lesson on its own or teach it prior to the lesson Multiplication: Musical Chairs.
Making mistakes helps us learn! Your students will flex their analytical muscles to pinpoint errors in multiplication problems using arrays. Use the lesson on its own or as support to Base Ten Arrays for Multi-Digit Multiplication.
The partial products strategy is essential for students to build a foundational understanding of place value as it relates to multiplication. This lesson may be taught on its own or used as a pre-lesson to Multiplying Multiples.
